It is performed by winding up a calibration probe 16 having a mass necessary for a calibration test determined by the ratio of L 2 and L 2 with a winch 13 and loading it on a lever 10 for calibration load via a rope wheel 11. Even during this calibration inspection, the output of the mass detection control device becomes a value calculated and converted by the ratio of the eccentricity e and the distance L 2 as described above.

Inspection can be done easily and in a short time. Also, the winch 13 is electrically operated,
Remote calibration inspection can also be performed by allowing the calibration probe 16 to be moved up and down by remote control.

精度が向上するという効果が得られる。FIG. 3 shows another embodiment of the present invention. In the above embodiment, the bracket 7 was linearly connected to the shaft 8. Instead of this, a rotatable link 18 was attached to the shaft 8 and the link 18 was attached.
In this example, the shaft 19 rotatably attached to the bracket 7 and the bracket 7 are connected. According to this, the hopper 1 in FIG.
Since the horizontal force that may occur in the horizontal direction does not act on the shaft 8, it is possible to obtain the effect that the mass detection accuracy is improved as compared with the one embodiment.
